摘　　要：无线通信系统经过多年的发展,各制式出现融合的趋势。同时运营商降低采购和运营成本的需求,使得支持多种制式、平滑演进的"软基站"成为无线基站演进的方向。文章对无线通信系统软基站的相关技术背景进行了介绍,并对实际软基站的架构设计思想、系统模块构成及关键技术等进行了提纲挈领地分析。文章指出未来软基站将继续向集成度更高、基带资源调配更灵活、传输方式更丰富、成本更低、节能更环保几个方向发展。With the rapid development of wireless communication systems,different standards have begun to be merged.Operators place stringent requirements on reducing OPEX and CAPEX,and as a result,soft base stations supporting multiple standards have become preferred.This paper introduces the background of soft base stations,then analyzes architecture design,system modules,and key technologies.It suggests the future development of soft base stations will tend towards more integrated,flexible deployment of resource baseband;abundant transmission,lower cost,and energy efficiency.
